Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: resistance value (3.01 kOhms), tolerance (±1%), package type (0805 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All substitute parts listed maintain these core electrical and mechanical specifications. Power rating variations (0.125W vs 0.5W) and feature enhancements (automotive AEC-Q200 qualification, pulse withstanding, moisture resistance) represent functional upgrades that do not compromise compatibility. RoHS and REACH compliance status are provided for regulatory assessment but do not affect electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring ROHS3 compliance and unlimited moisture sensitivity rating, all substitute parts except CRCW08053K01FKTA are suitable direct replacements. RMCF0805FT3K01 from Stackpole Electronics Inc provides automotive AEC-Q200 qualification while maintaining the same manufacturer lineage as the primary part. YAGEO AC0805FR-073K01L and RC0805FR-073K01L offer moisture-resistant formulations with AEC-Q200 certification for automotive environments. Vishay Dale CRCW08053K01FKEA and ERJ-6ENF3011V from Panasonic provide automotive-grade alternatives with identical electrical specifications. For applications subject to pulse stress conditions, CRCW08053K01FKEAHP and RCS08053K01FKEA offer 0.5W power ratings with pulse withstanding capability while maintaining the 0805 package footprint. CRCW08053K01FKTA is not recommended for new designs due to RoHS non-compliance and REACH-affected status.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FT3K01 be used as a direct replacement for RMCS0805FT3K01?

A: Yes. Both parts share identical electrical specifications (3.01 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C) and 0805 package dimensions. RMCF0805FT3K01 adds automotive AEC-Q200 qualification, making it suitable for automotive applications while remaining compatible with general-purpose circuits.

Q: What is the difference between 0.125W and 0.5W power-rated variants?

A: Power rating indicates maximum continuous power dissipation capability. The 0.5W variants (CRCW08053K01FKEAHP, RCS08053K01FKEA) can handle higher power dissipation and pulse stress conditions. Selection depends on circuit requirements; oversizing power rating does not degrade performance in lower-power applications.

Q: Are all substitute parts available in 0805 package?

A: Yes. All listed substitute parts are manufactured in 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), ensuring PCB compatibility without layout modifications.

Q: Which substitute offers the best moisture resistance?

A: AC0805FR-073K01L and RC0805FR-073K01L from YAGEO explicitly feature moisture-resistant thick film composition. All parts maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Is automotive AEC-Q200 qualification required for my application?

A: AEC-Q200 certification is mandatory for automotive applications. RMCF0805FT3K01, AC0805FR-073K01L, CRCW08053K01FKEA, CRCW08053K01FKEAHP, ERJ-6ENF3011V, and RCS08053K01FKEA carry this qualification. RC0805FR-073K01L and RMCS0805FT3K01 do not include AEC-Q200 certification.

Q: What is the temperature coefficient significance?

A: All listed parts maintain ±100ppm/°C temperature coefficient across the -55°C to 155°C operating range. This specification ensures resistance value stability across temperature extremes and is identical across all substitutes.

Q: Can CRCW08053K01FKTA be used in new designs?

A: CRCW08053K01FKTA is not recommended for new designs. It is RoHS non-compliant and REACH-affected, creating regulatory and supply chain risks. Use CRCW08053K01FKEA or CRCW08053K01FKEAHP instead.
